SWITCH.

Specification of Letters Patent.

Patented Aug. 14, 1917.

AppIication filed January 15, 1917. Serial No. 142,501.

To all whom it may concern:

Be it known that I, MAGLOIRE Mnrrror, a subject of the King of GreatBritain, and resident of 133 Queen street, West, in the city of Ottawa,Province of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Switches, of which the following is aspecification.

This invention relates to improvements in switches of the type describedin United States Patent No. 1,217 ,043, Feb. 20, 1917, from which thiscase has been divided.

The objects of the invention are to permit of the motorman actuating arail switch without stopping his car, to render the mechanism compact inconstruction thereby occupying a minimum of space, to obviate jarring onthe car during the operation of actuating the switch and generally toadapt the several parts to better perform the functions required ofthem.

With these and other objects in view the invention consists essentiallyof the improved construction particularly described and set forth in thefollowing specification and accompanying drawings forming part of thesame.

In the drawings,

Figure l is a fragmentary sectional elevation of a street car andrailway embodying the present invention.

Fig. 2 is an end elevation of the wheels adapted to actuate the switchmechanism.

Fig. 3 is a fragmentary perspective view of the switch and coactinglinks controlling the actuation of the same.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents a street car of any usual typeand B a railroad provided with switching mechanisms C adapted to becontrolled from the motormans platform D by the manually actuatedmechanism E. This mechanism E consists of a pair of wheels 10 and 11which lie in different vertical planes and are rotatably mounted on thebifurcated ends of the bell crank 12, the arms of which are offset toenable one of the wheels engaging and actuating one of the plungers 31or 32 of the road switching mechanism 0.

This bell crank is rigidly mounted on the shaft 13 rotatably supportedby the bracket 14 from the longitudinally extending bar 15 carried bythe brackets 16 mounted on the underface of the floor of the car A.

The bar 15 is provided with shoulders 17 adjacent to the ends thereofwhich coact with the brackets 16 and obviate l0ngitudinal displacementof the bar, while the downward motion is controlled by the pins 18extending through the brackets 16.

To obviate jarring due to the upward displacement of the bar 15 Iprovide spiral springs 19 located between the upper face of the bar andthe lower face of the floor of the car.

The shaft 13 is provided with a crank arm 20, which is pivotallyconnected to one end of the link 21, the other end of which is pivotallyconnected to one arm of the bell crank 22, rotatably supported by thebracket 23 from the bottom of the car A, the other arm of the bell crankbeing connected to the lower end of the link 24, the upper end of whichis connected to the disk 25 carried by the spindle 26, rotatablysupported in the quadrant 27 secured to the car A, adjacent to thecontrol levers, so that actuation of the said disk may be readilyaccomplished by the driver.

To facilitate rotating the spindle 26 and disk 25 to the desired extent,a lever 28 is provided carrying a suitable detent 29 adapted to engagewith the serrations or teeth 30 on the quadrant 27.

As the lever 28 is actuated in a vertical plane, motion is transmittedthrough the link 24 to the bell crank 22 and thence through the link 21to the shaft 13, rotating the bell crank 12 in a vertical plane and sopositioning the same that one of the wheels 10 or 11 will coact with oneof the spring controlled'plungers 31 or 32, which actuate thelongitudinally extending spindle 33 controlling the operation of therailway switching means C.

This railway switching means C is fully described in my United StatesPatent No. 1,217,043 and since it does not form part of the presentinvention, except in so far as it is actuated by the wheels 10 and 11 itis deemed unnecessary to further describe the same.

When the mechanism is in use and a car is approaching a switch, themotorman actuates the lever 28 to bring the desired wheel 10 or 11 intoposition to engage its coacting plunger and so set the switch in therequired manner.

It will be readily seen that during the rotation of the bell crank 12,the bar 15 which carries the same will be prevented from movinglongitudinally due to the shoulders 17 engaging with the edges of thebracket 16 and also any tendency of undue motion upwardly on the Wheelscoacting with their plungers will be overcome by the springs 19, so thatdisplacement of the several parts and jarring to the car is entirelyeliminated.

As many changes could be made in the above construction, and manyapparently widely diflerent embodiments of my invention, within thescope "of the claims, constructed without departing from the spirit orscope thereof, it is intended thatall matter contained in theaccompanying specification and drawings shall be interpreted asillustrative and not in a limiting sense.

'What I claim as my invention is:

1. A device of the class described comprising a bar longitudinallyextending and vertically displaceable with relation to the car, wheelscarried by the bar lying in substantially parallel vertical planes,means for simultaneously elevating and lowering the said wheels andswitch means operated by the said wheels.

2. A device of the class described comprising a bar longitudinallyextending and vertically displaceable with relation to the car,resilient means controlling the upward motion of the bar, a pair ofwheels carried by the bar adapted to lie in substantially paral lelvertical planes, means for simultaneously operating the wheels toelevate one and lower the other, and switch means operated by the wheel.

3. A device of the class described comprising a barlongitudinallyextending and vertically displaceable with relation to thecar, resilient means controlling the upward motion of the bar, meanslimiting the downward motion of the bar, a bell crank having offset armsoperatively supported from the bar, wheels on the saidarms, means forrotating the bell crank in a vertical plane, and switch means operatedby the said wheels.

In witness whereof I have hereunto set my hand in the presence of awitness."
